bgp sorted tables

[Daniel Suchy]

Hello,
other implementations has no problems with sorted output, even for
hundreds thousands of routes in table.

It also can be implemented as a some configuration option or as a
command parameter (something like "show ... sorted"), if you're worry
about significant performance degradation.

Unsorted route output is main problem, but I also pointed, that there're
other "show" commands, where sorted listing might be useful in some
cases from operator's perspective.

With regards,
Daniel
